PDF Merger
Merge multiple PDF files into one document securely in your browser.
📖 How to Use PDF Merger
Step 1: Select PDF Files
Click the upload area to select multiple PDF files. You can choose files from your Device Storage, Google Drive, iCloud, or Dropbox via the system file picker. You need at least 2 PDF files to merge.
Step 2: Arrange File Order
Use the up (↑) and down (↓) arrows to rearrange the files in your desired order. The files will be merged in the order they appear in the list, from top to bottom. You can also remove individual files using the "Remove" button if you change your mind.
Step 3: Merge and Download
Click the "Merge PDFs" button to combine all selected files into one PDF document. The merging process happens entirely in your browser using pdf-lib, so your files never leave your device. Once complete, the merged PDF will automatically download to your computer. You can add more files or clear the list to start over.

• The order of files matters—arrange them in the sequence you want in the final document.
• Large PDF files may take longer to process, but all processing happens locally for security.
• You can merge as many PDF files as needed in a single operation.

Frequently Asked Questions
Is it safe to merge confidential documents?
Yes, absolutely. Since our PDF Merger runs entirely in your browser, your files are never uploaded to our servers. They stay on your device throughout the entire process, making it safe for confidential business or personal documents.
Is there a limit to how many files I can merge?
No, we do not impose artificial limits on the number of files. However, performance depends on your device's memory (RAM), so merging hundreds of very large files might be slower on older devices.
Does this tool add watermarks?
No. We believe in providing a clean, professional tool. Your merged PDF will be free of any watermarks or PlayTool branding.
